Greasemonkey Seems To Fail With Too Many Gm_xmhttprequests?

Mar 22, 2006

I'm trying to write a script (my first) that loops through some table
rows and gets some data from another page using gm_xmlhttprequests. It
works if I keep the loop to one, but if I try and loop through all the
rows, and therefore have say 10-20 gm_xmlhttprequests, the script just
seems to fail. But if I put an alert inside each gm_xmlhttprequest, and
wait a bit before dismissing the alert, the gm_xmlhttprequest will
succeed and the data gets updated as planned. It seems as if the
gm_xmlhttprequests don't block, or the script keeps executing without
waiting for the requests to finish. I don't have any listeners on the
script, I just want it all to load when the page loads. Also, I looked
at the javascript console and it doesn't have any errors about the
gm_xmlhttprequests.

AppendChild In Greasemonkey

Jul 23, 2005

I'm using the following code in a Greasemonkey script.

var start, newElement;
start = document.body;
newElement = document.createElement('b');
newText = document.createTextNode("The Greasemonkey salutes you!");
newElement.appendChild(newText);
start.appendChild(newElement);

Can anyone tell me: 1) why my string appears twice; 2) how to make it
appear just once?

I'm trying to insert code at the top of every viewed page. Obviously,
document.body appends the string to the closing body tag which is not
what I want. What could I use to insert my code as the first childnode
under 'body'?

Replace Url Greasemonkey Script?

Feb 12, 2010

I am trying to learn some javascript at the moment and thought a simple greasemonkey script might be a good way to start.What I want the script to do is to replace an existing url on a website with a different url from another location within the website.

E.G. replace "/mailbox.php?inbox" with "/account.php?action=mybookmarks"

There are a lot of examples of replacing existing urls with different ones on the web but they all use id's to locate and replace urls.

This script is for a site I visit often and since I dont own it I dont have the ability to add id tags to the appropriate a tags, this makes writing this script a lot more difficult.This is the code I have so far;

Code:

// ==UserScript==
// @name NZBmatrix mailbox url replace
// @include http://nzbmatrix.com/

[code]....

Watching A Countdown Timer With Greasemonkey?

Mar 21, 2009

What I would like to do is watch a countdown timer on a page, like the ones on swoopo.co.uk and then perfom an action depending on what time is left on the timer.

I've installed DOM inspector on Firefox and poked around with javascript shell and I think I've figured out how to read the timer and assign that to a variable, something like this -

var timer=document.getElementById('counter_index_page_162980').innerHTML;

Now I need to watch that so I guessed this would do -

while (timer!=="00:00:01")
{
var timer=document.getElementById('counter_index_page_162980').innerHTML;
}
alert('timer at 1 sec!');

But that just brings up an "unresponsive script" error in my browser.

Am I even close to the mark? I know I'm not going to win any auctions with this but I've already paid for the bids so I may as well use them now.

Greasemonkey: Insert An Element Using Regular Expression

Nov 27, 2006

I'm a newbie to JavaScript and Greasemonkey and just started learning
with 'Dive Into Greasemonkey'. I looked for an example on the web, but
unfortunately I'm still missing something...

I have a text file which is a simple database:

Key01 Text01 Url01
Key02 Text02 Url02
....

I'd like to insert after

<a href="anUrl" class="thisClass">Key01<a>

the element

<a href="Url01">Text01<a>

I tried to reuse the "Dumb Quotes" from 'Dive Into Greasemonkey' by
replacing

replacement = {
"Key01":"Key01</a><a href="Url01">Text01",
"Key02":"Key02</a><a href="Url01">Text02"
};

Unfortunately, this doesn't work, since </a><a href...is not
interpreted as a HTML tag.

So I tried this:

nodes = document.evaluate(
"//text()",
document,
null,
XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
null);
for (var i = 0; i < nodes.snapshotLength; i++) {
node = nodes.snapshotItem(i);
text = node.data;
for (key in replacements) {
if(s==key)
helpkey=key;
}
newLink = document.createElement('a');
// newLink.href = 'Url0x' ????
// newLink.appendChild(document.createTextNode(Text0x )); ???
newLink.parentNode.insertBefore(newLink, node.nextSibling);
}

I'm really lost.

Greasemonkey - Display Number Of Clicks Since Last Refresh?

JQuery :: $ In Id Causes Selector To Fail

Jun 16, 2010

I'm trying to add some functionality to a existing application. I have no control over the input element ids. There are inputs I need to use that have $ in the id <input id='field1$0'>. Trying to use the id selector $('#field1$0') fails (result is undefined).Is this a bug or "by design" in qQuery?Is there a workaround, other than looping thru all inputs to find the ones I need?

DOCTYPE Causes Form To Fail?

Aug 2, 2011

I had to add the following DOCTYPE to a webpage in order for IE to parse my page design properly, and this caused the form on the page to fail in FireFox (which works fine without the doctype). The form works fine in IE.Here is the DOCTYPE I added to the top of the page;

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

The error log in FireFox says;

frmTest is not defined - Line 30

Here is the block of code it is referring to;

Fail To Make Key / Value Pairs?

Mar 28, 2010

I have the following form:

<form id="registrationForm">
<input id="forename" type="text"></input>
<input id="surname" type="text"></input>[code].....

...which suggests my JavaScript is partially working, but is failing on my attempt to make Key/Value pairs. Unfortunately, I'm not knowledgeable enough on JavaScript/DOM to identify an error and would be grateful if a more seasoned programmer could let me know the error of my ways.

Jquery :: Causing CSS To Fail Over SSL

Mar 29, 2010

I am using ASP.NET for data retrieval and jQuery to perform various functions/animations (error bar, slide menu, table sorter, etc...). Everything is working great until the pages are viewed over and SSL connection. When viewing over SSL, some of the margins/padding stops working and the hover effects on tables stop working correctly (leaving cells coloured, not colouring others). After spending a day looking for the solution in Google, I haven't found anything that will fix the issue. No errors/warnings are displayed on the page.

CreateElement And Nodes Fail In IE?

Jun 1, 2010

I'm having trouble parsing through a table in I.E. Of course it works fine in firefox and chrome. I'm pulling html off of a txt doc and storing it in a temporary div made with createElement so I can go through and parse out the data. Code is below:

[
Code:
var tempdiv = document.createElement("div"); //create temporary element to store html content in
tempdiv.innerHTML = html; //dump html content into new element

[Code]....

It returns 0 for rows and and cols. If I use a getElementsById and grab a table already on the page it works fine.

XmlHttpCreate Function Ie6 FAIL

Jul 12, 2010

I'm trying to GET or POST a request to a server. The code below works fine in Firefox, Safari, Chrome and IE7+ but fails in IE6 in spite of the xmlHttpCreate function being copied and pasted straight from Microsoft's MSDN site. The place where IE6 fails is on the oReq.send() line. It appears to create an activeX object but just won't send it. I have also tried oReq.send(null) and oReq.send("") but neither works.

Cookies Fail When Using URL Frame Re-direct

Apr 22, 2006

I have a simple html document I have been using for some time on my
(i.e.) abc.com domain that uses cookies. I recently purchased a new
domain name and set up a service to redirect my new domain (i.e.)
xyz.com to a sub-directory of the abc.com domain. In other words, when
someone goes to URL xyz.com, they really end up in abc.com/xyz
directory but the MSIE browser says they are xyz.com.

The problem is that cookies quit working in this setup when I copied
the same HTML document in the /xyz subdirectory that xyz.com now
accesses. I can't set or get a cookie any longer by calling the
document.cookie function from JS any longer. The call does not fail
but the data is always blank. I even tried setting the cookie and from
the next line of code reading it back immediately and it still would
not save the cookie.

Anyone know how to fix this?

I checked the value of location.host, .hostname .pathname,
document.domain and they all indicate I am really at abc.com even
though the address in my IE browser says I am at xyz.com.

Anchor Objects Referenced By Name Fail In IE?

Aug 7, 2010

for an anchor object, it is ok to reference by index. But when referenced by name, it seems unavailable in IE8 (not sure abt other IE version). I tried FF, it works well. So is it an IE bug or something?
<a name="thisAnchor">HERE</a>
<script language="javascript" type="text/javascript">
alert(document.anchors[0].nodeType)
// no problem in IE and FF
alert(document.anchors["thisAnchor"].nodeType)

Ajax :: Firefox Call Fail ?

Mar 12, 2010

I have an Ajax call and it keeps return nothing versus some text when the ready state is 4, and the status is 0 inside Firefox 3.6.

I debug the server and it did return some text. The browser just doesn't expose it.

The JSP code is in a Weblogic server in port A, the JS code is included in the JSP coming from Weblogic port B (2nd server, same host). The Ajax call URL is on the same Weblogic server/port B as the JS. The Ajax call is started from a click on a button from the JSP page serving on port A).

Here are the configurations that works with the identical code:

1) Exactly like above using Internet Explorer

2) Exactly like above using Firefox, with the exception that the server is OC4J versus Weblogic

3) Exactly like the above (Weblogic), with the exception that the JSP and JS codes are in the same (single) server/port and using Firefox browser

So this is very strange. The same Weblogic server would work if all files are in a same server. In any case, the server code always work, and always return valid value (I wonder if some header is different). In fact IE works.

I think it's maybe security issue of Firefox handling of 2 servers. However, the same Firefox does work with OC4J servers.

Preventing Onkeypress Events In Netscape 7 For Mac Fail

Jul 23, 2005

I have a web page where I want to intercept keypress events in an INPUT-tag
and check if it is the Enter key, which calls another function that executes
a search. My code runs on Netscape 7 for Windows, IE 6 for Windows and IE5.1
for Mac, but not on Netscape 7 for Mac. When I press the Enter key, the
event gets caught but it does not get prevented and the search is never
executed.

The code looks like this:

function KeyDownHandler(e)
{
// if not Netscape, get IE event
if ( !e )
e = window.event;
if ( !e )
return true;

// Get valid ascii character code
var key = typeof e.keyCode != 'undefined' ? e.keyCode : e.charCode;
// process only the Enter key
if (key == 13)
{
// cancel the default submit
if (e.preventDefault)
e.preventDefault();
else
window.event.returnValue=false;

// submit the form by programmatically searching
search();
return false;
}
else
{
return true;
}
}
